That is one of the more ridiculous things I think I've read on here.

So you're saying that with a heavy load, your transmission downshifts from
overdrive when on a hill? Ignoring the fact that typically with a heavy
load you should shut off the overdrive, I would tend to think that
downshifting out of overdrive on a hill with a load isn't really something
that I would consider the vehicle to be regeared.

Is it just me or does this sound kind of ridiculous?

The math for those tires would be 3.07*33/27.7 = 3.66. So to keep it
like stock you would use 3.73. Numerically higher if you want get your
RPMs higher on the highway or for better off road performance.

I run 33's with 4.10 gearing and for me its a perfect fit for an all
around vehicle. I had 31's with 3.07 gearing and hated it after a
awhile
Not sure if your year/type wrangler came as a 4 cyl but you could
swap in some 4 cyl axles with 4.10 gears. I did on my YJ.Best upgrade
I ever did.
Thats what I did before I got my 8.8 in the rear :-)

Not sure if your year/type wrangler came as a 4 cyl but you could
swap in some 4 cyl axles with 4.10 gears. I did on my YJ.Best upgrade
I ever did.
Thats what I did before I got my 8.8 in the rear :-)

As long as everyone and their dog is jumping in here 3 times, I may as
well add my 2 cents. I have a CJ7 running 33s and 4.10 gears, used to have
2.73s, daughter has a YJ running same 33s, she has 4.88 gears down from
4.10s, both act about the same on and off road as stock, both locked front
and rear. Go 4.56 or 4.88s.
